The third Lifelog Search Challenge (LSC'20) took place on the 30th October 2020 and was a fully virtual event. It started at 8am (Irish Standard Time) and finished at 2pm. LSC'20 had a total audience of over 150 attendees ands streamed live at the twitch URL ( There was an accompanying Whova app for the LSC'20 workshop that provided a schedule, speaker profile and links to the ACM Digital Library which was open access on the week of ICMR'20.
As with all previous versions, LSC'20 was a highly interactive and entertaining workshop modelled on the successful Video Browser Showdown annual competition at the MMM conference. LSC is a participation workshop, which means that all participants will write and present a paper, as well as taking part in the live interactive search challenge. Consequently, the workshop will have two parts, (1) oral presentations, and (2) the search challenge.
The format of the workshop was as follows:
  • A conventional first session with an introduction speaker, a panel discussion and oral presentation of research papers with a paper from each participant.
  • A second session which is the interactive search challenge, which will be open for all ICMR'20 delegates to attend. All participating groups will take part in the real-time competition, which will be configured in the manner described below.
The oral presentations (with associated papers) described the approaches taken to develop the interactive system for the search challenge. The workshop has an associated LSC dataset (see DATA page), which will be a new four month lifelog dataset.This dataset consists of rich multimodal lifelog data (wearable camera images, user activities and locations). Associated with the dataset will be 6 test and at least 18 evaluation multimodal topics representing challenging real-world information needs. We intend to use both expert and novice users for the search challenge.
The first LSC workshop was hosted at ACM ICMR 2018 in Yokohama, Japan. The
LSC'18 webpages are archived for historical purposes. The second LSC2019 workshop took place at ACM ICMR 2020 in Ottawa, Canada and the LSC'19 webpages are also archived. Additionally, for the WSDM Task Intelligence dataset, please see the LSC'18 pages. These archived pages describe a password protected dataset that was used for both the LSC2018, LSC2019 and the WSDM-Task Intelligence challenge at the Task Intelligence workshop at WSDM 2019. The Proceedings of LSC'18 and LSC'19 are available on the ACM Digital Library.
